REVIEW OF CARDIOVASCULAR DISEASE IN ALLERGY
William J. Rea, M.D., F.A.C.S.
An exciting era is dawning in medicine. The merging of thought in the field of allergy, immunology, cardiovascular disease, and nutrition is opening up new vistas. It appears as if many of the inflammatory vascular diseases of unknown etiology may now have a potential of having their triggering agents defined. Capability of incitant definition not only would be a significant aid in treatment but would also allow us to advance further than ever before into the less costly areas of preventive medicine.
Many recent developments have allowed us to more clearly define incitant triggering. Detailed description by Randolph(1) of how to construct a totally controlled environmental unit has for the first time allowed us an exceptional tool to study inflammatory cardiovascular disease under environmentally controlled conditions. The development of the ability to measure numerous laboratory parameters such as immunoglobulins, total hemolytic complement and all its components, T and B lymphocytes, blastogenesis and numerous mediators such as kinin, serotonin, and histamine was critical. These developments have allowed us to track and plot challenge reactions induced under well-controlled conditions, thus giving us laboratory support of observed cause and effect phenomenon. Pathological studies developed by Zeek(2) and Parrish(3) and amplified by many other authors(4),(5), (6) allows us to even have biopsy verification in many cases.
Over the past two years, over 217 articles have been written on the subject of inflammatory vascular disease. Most of these are included in the bibliography. Since it is impossible to review all of the articles in the allotted pages in this section, a summary of concepts put forth in these articles will be given. To understand the scope and necessity of defining environmental triggering agents, it is important to understand the spectrum of inflammatory vascular disease (FIG. 1). This patho-physiology of blood vessel change is a spectrum of reversible to totally irreversible changes. Initially, after insult, localized edema or hives is well appreciated. However, the much more common but less well appreciated subtle generalized edema is often ignored. This usually occurs in the extremities and the periorbital areas. The poor understanding probably develops even though the triggering agents may be similar in both because of unawareness that generalized edema may develop into much more serious disease. The blood vessel wall develops greater leaks or even ruptures as the disease progresses, resulting in red blood cell extravasation with bruising, purpura, and petechiae.
Later, as the fibrinolytic system becomes depleted, clots occur and palpable purpura develop. Eventually, if the vessel is injured enough, ischemic necrosis can occur. If the area survives, granulomatous healing may occur. Atherosclerotic plaque formation can occur in other people after severe inflammation develops.
In inflammatory vascular disease, two different cell types occur. The lymphocytic type infiltrate will occur around the vessel wall. At first this appears as a mild form of vasculitis. However, this disease may smolder along for years and then suddenly accelerate into disabling or irreversible inflammatory
disease. The leukocytoclastic form appears to be more acute and perhaps more devastating initially. Here, the leukocytes occur around the vessels and then break up. The debris is incorporated into cells, thus the name leukocytoclastic.
Unfortunately, vasculitis in some circles has come to mean only the necrotizing variety. The bulk of the recent research has been done in this area. However, it is important to perceive that the non-necrotizing varieties exist and may well be more important than the necrotizing in that these may be a prodrome of more serious diseases and, thus, if diagnosed and treated early, are more easily preventable.
Internal disruption of the homeostatic mechanism that causes vessel damage may occur from any of several pathways (FIG. 2). Most of the past research has been devoted to delineating the first four mechanisms. It may be, however, that the bulk of vessel disruption is through the fifth or mediator systems. The research thrust in this area is just beginning to occur. Already Buisseret(7) has shown prostaglandin inhibition by preloading food-sensitive people with aspirin and indomethacin. Polish investigators have also shown kinin triggering in some patients after incitant challenge.(8)
For the last 70 years there have been isolated reports in the literature of environmental incitants causing vascular phenomena. The most noteworthy of these were by Hare(9), Schofield(10), Harkavy(11), Rowe(12) and Coca(13). Recently, renewed interest has occurred in defining noninfectious incitants and thus eliminating causes of diseases. This appears to be the direct result of several recent papers. Yevick,(14) at the Woods Hole Marine Biology Center, found the cardiovascular system of sea life exposed to oil spills to be severely affected. The vessels developed inflammation and resultant fibrosis. This appeared to occur more often with animals near the center of a spill. Taylor(15) then reported a fatal cardiac arrhythmia in a teenager after inhalation of a fluorocarbon spray. Later, increase in arrhythmias after prolonged use of the fixative for the frozen section machine were noted among a group of pathologists.(16) Stewart(17) also reported a fatal arrhythmia due to furniture removal substance. Boxer(18) and Klotz(19) both reported patients with arrhythmia due to environmental incitants. Rea(20) has shown a spectrum of arrhythmias that were induced while patients were under rigidly controlled conditions. These were done in a double-blind manner and appear convincing since they are reproducible.
The following case report is illustrative of what one might find by looking for environmental incitants.
This 42 year old female nurse had a 20-year history of recurrent sinusitis treated with antihistamines. No attempt was made to determine the etiology. She then developed severe lower extremity peripheral vascular spasm accompanied by tetany of the gastrocnemius muscle (FIG. 3). This was so severe that it required narcotics to control the pain. After 2 ½ years of this, severe angina developed and coronary angiograms revealed spasm of the left anterior descending coronary artery (FIG. 4). Placement in the Environmental Unit revealed the following laboratory work:
|WBC mm3||5, 100|
|T-Lymph E Rosette||41%||60%|
|B-Lymph EA Rosette||45%||20-40%|
When studied in an environmental unit, one can observe sequential reactions such as was seen in this patient. The length of reactions would be from five to 110 hours. The sequence would be as follows: incitant challenge, immediate tickling in the throat with hoarseness, nausea and vomiting, shortness of breath, loss of peripheral pulse in 15 minutes, then spasm of gastrocnemius with severe tetany followed by a spontaneous bruise (FIG. 5) at five to twelve hours after challenge. C3 was changed during incitant reactions (FIG. 6 and 7). The patient was found to be sensitive to picomolar challenge of the pesticide methachlor. Her T-lymphocytes and serum Ca++ dropped on at least four separate ambient dose challenges. S-T depression occurred if reactions were severe enough (FIG 8). This patient had five foods out of 42 challenged and 12 synthetic chemicals out of 14 challenged that reproduced her symptoms.
One can see that, because of complexity of the disease and number of incitants involved, without a controlled environmental situation, this type patient would not have had her etiology defined. She would have been relegated to the insolvable category with more symptomatic treatment being given and observed as her health continued to deteriorate, as was seen over the previous several years.

Finn(21) has confirmed cardiac environmental triggering by reporting a series of patients who were sensitive to foods and developed arrhythmias after double-blind challenge. Levy(22) recently reported histamine release in animals with coronary occlusions, and thinks that perhaps more cardiac arrhythmias and myocardial infarction should be ascribed to the hypersensitive mechanisms. In view of present knowledge, it certainly appears that the clinician will better be able to define triggering agents of cardiac disease if he will only look for them. If he understands the four basic principles he will have reproducible results. These principles are: (1) four-day avoidance before incitant challenge; (2) any trigger is possible including pollens, dusts, molds, terpenes, foods, or chemicals, and they are frequently multiple; (3) that responses can occur anywhere from five seconds to fourteen hours after a challenge; and (4) that the chemical environment must be well-controlled in a less polluted manner. He must also be cognizant that most of the reactions are not IgE mediated, though this does frequently occur. The most important perception that has evolved from this base of knowledge is that no matter what internal mechanism is disrupted, the search for triggering agents should be carried out before these secondary mechanisms become autonomous and cause irreversible changes in the tissue.
When considering the response of the cardiovascular system to incitants, one must perceive that any part of the system can be involved. Therefore, some patients may just exhibit heart involvement while others will show just venous involvement or small or large peripheral arterial involvement. Some patients can show a combination of any or all parts at the same or different times in the course of the inflammatory vascular disease. For example, a patient may have phlebitis at one time and spontaneous bruising at another, or they may occur together. Reynaud's phenomenon or hypertension may be present with cardiac arrhythmia or they may be isolated.
LARGE VESSEL INVOLVEMENT
Large vessel involvement has been shown to occur with sensitivity to drugs such as Ergot22 and Coumadin(23). This author(24) has reported several patients with triggering agents due to foods and chemicals.
Grant(25) has now reported many patients with vascular headaches who were sensitive to multiple foods and chemicals. These substances were other than the commonly known monoamine oxidase inhibitors. She found that though the patients improved with elimination of cigarettes, Ergot, and birth control medication, they did not usually get totally well until food and chemical sensitivities were brought under control. The following are typical case reports of large vessel involvement.
Case 1: This 65-year old female presented with a five-year history of joint aches and calf cramps. She also noticed some "senile purpura" along with high blood pressure. After being in the Environmental Unit, off all medication, she cleared her symptoms. The blood pressure dropped from 210/120 to 130-80 and a return of dorsalis pedis and posterior tibial pulses from 0 to 4+occurred. She also lost her purpura after being in a basal state for several days. Challenge with corn gave the following sequence of events: immediate hoarseness; in five minutes, abdominal distension developed; within 1 ½ hours, 20 diarrhea stools occurred; blood pressure went from 130/80 to 180/120. Peripheral pulses were lost at two hours (FIG. 9) illustrated by an angiogram showing spasm of the tibial arteries, and then purpura occurred at five hours. The whole sequence terminated 24 hours after it started with a return of all parameters to the baseline.
This patient was sensitive to 10 of 40 foods tested and three of eight synthetic chemicals tested (Table I). She also showed linear changes when plotting complement and eosinophils (FIG 10). The hypertension was reproducible with five foods as well as three positive chemical challenges on 30 separate occasions (FIG. 11). It has appeared over the three year follow-up that the hypertension is totally related to incitant sensitivity. Biopsy of the purpuric lesion showed a lymphatic infiltrate around the vessel wall with edema and extrusion of red blood cells. No necrosis was seen.

Frequently, cerebral vascular involvement will also occur, and one sees isolated areas of the brain involved giving specific symptoms. The following is an example of this type involvement:
Case 2: This 42-year old surgeon was well until he developed asthma while in Vietnam. This was originally attributed to mold sensitivity but later it was perceived that he had been sprayed with 2,4,5, T (agent orange). Fat biopsies and inhalation challenge suggested the latter to be the primary cause. Carotid arteriogram during one of these spells revealed decrease in left carotid and left intracerebral flow (FIG. 12). The patient also developed spontaneous bruising, petechiae, and acneform lesions. After being placed in the Environmental Unit, off all medication, his symptoms subsided. He was able to rotate his arm and hand 40 times without the previously described clonic-like movements, a function he previously could not do. Double-blind challenge with certain foods and synthetic chemicals revealed the following sequence: Challenge with immediate right-sided peripheral cyanosis, then tenderness in left neck, decrease of superficial temporal pulse, then loss of use of right arm and hand followed by severe digital edema and very foggy thinking.

The large vessel involvement may be more devastating since major organ supply is affected. It is possible for organ ischemia and/or necrosis to not only result in severe disability but also even in death The common incitants were always multiple with all three major categories of incitants involved (inhalants, foods, chemicals). Usually, there were distortions in the eosinophilic, complement and T-lymphocyte systems.
Parish(26) showed small vessel triggering due to various antigens in several animal studies. He further showed deposition of numerous substances such as IgG and C3 on vessel walls. Theorell(27) has now shown triggering of small vessel vasculitis due to birch tree pollen, foods, and chemicals in humans. These were leukocytoclastic types, one of the cellular types Parish has previously described in animals. The following is one of his case reports illustrating the multifactoral nature and need to clearly define all incitants.
Case 2. (E. J. born 1925) is a man who had diphtheria in 1946 and malaria in 1955, now healed. From August 1969 he has recurrent attacks of a cutaneous necrotizing leukocytoclastic angiitis with purpuric, nodular, ulcerating or angioedematous skin lesions (FIG. 13), myalgia, rhion-conjunctivitis, dry cough without ronchi and also hyperistalis. Total serum IgE level is elevated (660-2080 U/mi, N 500). Except for dental root infections since 1972, no other infections, no tumors, autoimmune diseases or drug intolerances are found. Chest x-rays show stationary emphysema in left inferior lung lobe. Nodular skin eruptions after tooth extractions and strong Arthus type skin test reactions to staphylococic toxoid, tuberculia and Candida antigens indicate significant allergy to microbes. ESR is 10-35 mm. During 1973 reduced C3 level (31%, N=60-140%) and hyperfibrinogenemia (maximum 660 mg%, N320 mg%) are seen. Levels of total serum IgG, IgA and IgM, alpha1 antitrypsin and alpha2 macroglobulin are normal.
During attack period in February 1973 euglobulin lysis time indicates normal fibrinolysis activation by venous stasis. Intradermal test with 4 U kallikrein gives a local necrotizing vasculitis after 24 hours.
The patient avoids eating pears and legumes since they give diarrhea. Several vasculitis attacks anamnestically follow-up visits to a flat with animal hair carpets and also appear within birch and grass pollen seasons. During autumn-winter seasons remissions of more than a week are seen when the patient stays in dust-free environment and keeps to goods he tolerates. Intradermal allergen tests in February 1974 show reactions of macroscopically purpuric type within 3-24 hours to horse and cow dander, sheep wool, house dust, aspergillus, brewer's yeast, vegetable mixture and grass pollens. Traces of reagins and elevated IgG-antibody tire against sheep wool are found in serum in June 1974. Dietary regimen, according to anamnesis and result of skin test, reduces skin eruptions from 40-200 new nodules per day (1973) to none during up to 10 days when observed in hospital stay in February 1974. During this month skin eruptions were observed after the patient has eaten corn products (4 times) and pears (2 times) and when he had shaken a sheep wool carpet."
Rea(28) has shown similar events to occur using extremely controlled double-blind conditions. A lymphocytic non-necrotizing vasculitis was also reproduced in some patients due to food and chemical incitants as well as to various pollens, dusts and molds.
It appears that it would be prudent to now examine most patients with small vessel inflammatory disease for multifactoral incitant triggering.
It is now generally accepted that there are several varieties of necrotizing vasculitis. Originally, those were all lumped under the title of periarteritis nodosa. However, with careful scrutiny, some patients have been divided out. Many classifications exist, however; Table II is an adequate working one. Though the bulk of research is centered here, unfortunately, no emphasis has been placed on the definition of triggering agents in these types of entities. The best appreciated cause and effect relationships existing in the necrotizing vasculitis are in systemic lupus erythematosus. Here, numerous drugs have been shown to trigger the autoantibody reactions or events appearing similar, with resultant vessel wall disruption.(29)
Our group has seen one patient with temporal arthritis and three with systemic lupus that were apparently triggered by certain inhalants, foods, and chemicals. In view of Theorell's reports, our unpublished cases and those drug-induced lupus', it would be logical for all the necrotizing vasculitis to be examined for triggering agents.

Venous disease and environmental triggering has been sparsely reported in the literature. Earlier in the century, Conners(30) and Harkavy(31) reported cases of phlebitis due to foods. Many investigators including Zeek have recognized that some patients will have episodes of phlebitis during the course of their vasculitis if observed over a number of years, but they suggested no etiology.
Rea(32) has had an opportunity to observe several patients who presumably had intractable non-traumatic phlebitis. The majority of these patients were able to have their phlebitis cleared without medications while in a rigidly controlled environment. They also had their phlebitis reactivated with double-blind incitant challenge cleared within 48 hours without medication. This series of eight patients is contrasted to a parallel group of patients who were also sensitive to many incitants but who chose to ignore the avoidance of them and use medication for treatment. This group of eight patients had over 40 episodes of hospitalization plus countless periods of incapacity at home during a similar period of time. These were for recurrent phlebitis and pulmonary embolism. The two groups were about equal in severity at the onset of the study. In fact, the environmentally treated group appeared to be a bit more severe.
It is quite clear that attention to defining triggering agents in non-traumatic phlebitis can decrease the cost of medicine as well as relief of the morbidity and, possibly, even mortality.
The following case is an example of environmentally induced phlebitis. This 33-year old female had a gradual onset of diarrhea, followed by sinusitis and spontaneous bruising. These occurred over a period of three years with only symptomatic treatment being given. As she deteriorated, she developed recurrent phlebitis and pulmonary embolism. She had been hospitalized six times in the previous year before she entered the Environmental Unit. She also was totally incapacitated at home between admissions. All anticoagulants had failed. After five days in the Environmental Unit, all symptoms and signs had cleared and the patient, who could not formerly walk, could now not only walk freely, but could now ride a bicycle for six miles without problems. Double-blind challenge with chemicals revealed the patient to be sensitive to phenol, pesticide, and natural gas. Also, numerous foods have been incriminated. This patient has been totally asymptomatic for the last 3 ½ years and works every day. She has used no medication. It is now clear that any patient with indication of inflammatory vessel disease should have an intensive search made to define triggering agents. This should be done methodically and under as controlled conditions as possible before patients are doomed to a prolonged course of drug therapy which may last for years to a lifetime.
|T-Lymph E Rosette||538||1800 ± 200|
It should be emphasized that the IgE mechanism does not necessarily play a large part in determining incitants of cardiovascular diseases. Many other mechanisms are involved, and cause and effect incitant challenge, rather than the mechanism, should be the common denominator in describing the onset of disease.
ENVIRONMENTAL PRINCIPLES AND FACT - A NEED IN INFLAMMATORY CARDIOVASCULAR DISEASE FOR STUDIES UNDER BETTER CONTROLLED CONDITIONS
When analyzing and considering whether environmentally triggered vascular disease is a factor in a given patient's illness, the clinician must perceive several principles.
First, he must realize that medical environmental technology is about 100 years behind environmental technology. Since our technology and overview is not well developed, it hampers us in diagnosing and treating disease caused by noninfectious processes. The environmentally contaminated situation present today would be similar to the time when people were rubbing manure into wounds, or physicians were doing pelvic exams after a postmortem, as was done 100 years ago before the germ theory became well understood. Also, the public, as well as the medical profession, is generally unaware of potential environmental triggering agents. These substances are readily found in homes, workplaces, and even in hospitals in such abundance at times as to negate all attempts at diagnosis and treatment with hope for recovery in many patients. Thus, an individual with environmentally triggered disease may be sensitive to natural gas but, when being exposed to it 24 hours per day because it heats his home, water, and food, may not perceive the acute cause and effect relationship. This may also be true in the individual sensitive to the chemicals in his water supply who is exposed so frequently because he uses it in his food, drinks it, and bathes in it.
The second principle that should be kept in mind is the concept of the total body load which tends to distort many of the body's homeostatic mechanisms (FIG. 14). This is the sum of all incitants that the body has to handle in order to function. This is the total of the pollutants in air, water, and food. The load principle seems simple until one perceives the amount and scope of pollution that has crept into our environment. The more important components comprising the total load are discussed in the following paragraphs.
pollen, dust, mold
Fig. 14: Total Body Load
Most public water systems are now overloaded with synthetic chemicals which will increase the body load to synthetics from 1,000 to 10,000 times (Table III). Unfortunately, public water supplies are rated only to bacterial contamination, with chemical content being ignored. Recent E.P.A. studies(33) of the 83 largest cities show all of the water supplies to be severely chemically contaminated. Apparently, our waters are now as badly polluted with chemicals as they were with bacteria years before the advent of chlorination.
Ninety-four percent of the commercial food has pesticide in it.(34) It is also estimated that the average individual ingests one gallon of food additives per year.
In addition, the air in cities of 50,000 population or more has an outside air pollution gradient as compared to sea air of 150 good days to 2,000-4,000 on average to bad days(35) (Table IV).
The average home appears to be the most polluted place in our environment. The fact that homes are being built more airtight tends to increase pollutant contaminants. They contain high outgassing synthetics such as dyed nylons, polyesters, foam rubber beds, chairs, floor mats, etc. and, in addition, many have gas or oil heat, which further complicates pollution (Table V).

The summation of all these facts, plus a polluted work environment, makes a massive increase in body load that the individual has to handle just to function daily. This often becomes too great in people with certain hereditary and acquired tendencies resulting in individual susceptibility, thus allowing inflammatory diseases to occur. This chemical overload often distorts the food handling mechanism to the point that no foods are safe for some individuals. Often, people with chemical overload will also become quite sensitive to pollens, dusts, and molds.
The third principle is that of masking or adaptation where a person comes into contact with a substance and perceives no harm because there is not an immediate reaction.
This occurs if he is exposed daily or more often. In contrast, if he avoids the substance for four days, he becomes unmasked. Then, if he takes the suspected substance into his body, he will have an immediate and clearly definable reaction if it is harmful to him. In this way, cause and effect is easy to establish. Often, food sensitivity is missed because the individual is eating the offending food daily or more often, thus causing symptoms to be masked. This masking principle is commonly understood in the individual who is addicted to drugs. Here, in order to feel better, the individual often takes drugs whenever he has symptoms. If he omits them for four or five days, he has severe withdrawals. Some painters and battery workers say that the substances they work around bother them after returning from vacation until they get "used" to the offending substance again. Once they are "used" or masked they do not perceive the harmful effects any longer and they do well until they eventually develop inflammatory disease. At this time, then, since they are masked, they do not perceive the cause of their disease. We have seen several patients who exhibited this phenomenon while in the environmental unit.
The fourth concept is that of bipolarity. Often, the individual will have a stimulatory reaction and perceives the substance as not harming him initially, but actually making him feel good. However, after a period of time, be it minutes to years, his body's defenses break down and he has harmful disabling withdrawal symptoms. This is a well-recognized principle in cigarette, narcotic or alcohol addicts but not well known, yet just as prevalent, in plastic workers, painters, food addicts, and many other individuals who constantly inhale or digest toxic substances.
Once the aforementioned facts and principles are understood, study for incitant susceptibility must be done in meticulous detail in order to discriminate and clearly define particular triggering agents.
Each category of air, food and water will be discussed separately in order to consider all parameters. It should be pointed out that one must consider all parameters of equal importance in order to successfully diagnose and treat patients with environmentally triggered inflammatory vascular disease. Failure to consider all parameters usually results in a continuation of the disease processes, and eventual failure of overall treatment. This, though usually blatantly evident, may take years to perceive in some patients.
This parameter is the most difficult to assess because little attention has been directed toward air analysis of indoor pollution and because the outside air in the United States has become so polluted. According to some authorities, there has been no fresh air in this country in fifteen years.(36)
In order to study the environmental problems better, the Brookhaven Environmental Unit was created, taking into consideration the aforementioned facts and principles while using material constructed with meticulous detail. A description of the unit follows so the physician can use the principles in his office practice. Inattention to controlling the ambient air of an office will often result in misdiagnosis and, therefore, inappropriate treatment of many individuals.
Outside air is analyzed for the major pollutants such as nitrous oxide, sulphur dioxide, ozone, chlorine dioxide, cyanide carbon monoxide, and carbon dioxide.
A wing of the hospital was used to exclude contaminants from other parts of the hospital. A firewall was used in order to exclude all possible pollutants. Double doors were used so that an air lock could be obtained to stop outside air in the adjacent building. Air conditioning is local window units using all metal coolers. Heat is of local nature and presented a much more difficult problem since so many chemically susceptible people are sensitive to many types and sources. We have found that approximately ninety percent of 400 consecutive chemically susceptible patients are sensitive to the fumes of natural gas. This correlates with Randolph's findings. In addition, many patients are also sensitive to the fumes emanating from different electric devices. Copper radiators with aluminum fins are only satisfactory for fifty percent of our patients. Steel and cast iron radiators appear better but have a central blower which presents a problem. Radiant glass and ceramic are also available and are tolerable to many individuals. High temperature wires appear to be the most offensive form of electric heat (Table VI). Solar heat, when available directly, appears to be very acceptable.
DOUBLE-BLIND - 1 HOURS EXPOSURE
Bedding and draperies are cotton, linen and/or silk. No synthetics are allowed because of their high fuming properties.
Air depollution devices are used intermittently to clean outside pollutants. Unfortunately, these cannot be left on at all times because many patients are sensitive to the substances which emanate from the units.
Materials in these devices should be inert, preferably of metal and stone. Electronic filters are not advisable unless other filters are used distal toward the room. They should be rated to remove the ozone and phosgene which occur with the electronic filters.
HEPA filters seem to be the most toxic of the filters, apparently because of the glues that are used to hold paper together.
Currently, we are using sequences of filtration such as cotton or fiberglass as a prefilter followed by aluminum oxide impregnated with potassium permanganate. Then, a loose charcoal filter is used as the final pathway. These should all be in metal cages. Many patients have become sensitive to charcoal from either the pure coconut or bituminous coal origin. Ideally, cotton, marbles, and dechlorinated water should be used to remove the charcoal particles.
Basically, rooms can be made from any inert material. However, only four or five are easily available.
Air in the rooms is assessed by several parameters. The first is whether environmentally susceptible patients clear their symptoms in the rooms, and secondly, whether their abnormal laboratory tests return to control level without medication. The third parameter is direct analysis obtained by using gas chromotography and mass spectrometry. Unfortunately, not all parameters are easily available for air analysis. Some easily measured parameters are shown in FIGS. 15, 16, 17, 18 and 19, while changes in patients' serum returning to normal without medications are shown in FIGS. 20, 21, 22 and 23. It is even more important to stress the measurement of organics such as aldehydes, pesticides, phenols, benzenes, etc., since these are common contaminants of indoor air pollution. Failure to properly access these organics appear to be the single most common error in attempting to create a controlled environment, whether in the hospital, home, or office. A large proportion of the diagnosis and treatment of inflammatory disease falls into a lack of appreciation of these facts. Particulate counts, barometric pressure and relative humidity are constantly monitored.
Since there are now large amounts of additives, preservatives, pesticides and herbicides in commercial food, testing must be done with less chemically contaminated foods. In our center, an organization had to be started to foster the acquisition of such food. Farmers were contracted to grow the food in a safe manner. No herbicides, pesticides, or artificial fertilizers are used in growing this food. Food must be stored in uncoated cellophane and glass in order to prevent contamination.
Cooperatives are necessary in order to have available safe food and also to monitor the food to ensure a less chemically contaminated form. We have seen several examples of contaminated food found by this method. One time, many individuals began reacting to pork. The individuals knew they were safe on pork and that it must be contaminated. The farmer was contacted and informed us that he had acquired six-week-old pigs from another farmer and placed them on our usual feeding regime. Apparently, the gestation time and first six weeks feeding on chemically contaminated food was enough to severely contaminate these pigs. A second example was when many people were reacting to cantaloupe from a recent lot. Chemical analysis showed two parts per billion of dieldrin and chlordane. By using such a network of analysis, one can constantly monitor and help prevent food contamination.
Food for testing must be cooked in the patient's water, using either steel, iron or glass cookware in order to prevent further contamination.
It has become evident that many people are becoming increasingly sensitive to minute water contaminants. Recent studies show that most of our largest cities have severely chemically contaminated water supplies. We are now at the point of chemical contamination in water where we were 75 years ago with bacteria before the onset of chlorination. Little is recognized of the potential harmful effects of the chemical contamination of the water supply by the average layman or physician. In the Environment Unit, acute cause and effect for water contaminants can be ascertained in approximately two days. Double-blind studies using tap, charcoal filtered, numerous spring and distilled waters has revealed approximately ninety percent of the chemically sensitive patients to be intolerant of tap water. Some patients are very sensitive to distilled water while others may be sensitive to many of the spring waters:
c) Spring - 10
Spring water appears to be the best of the alternate waters. This correlates well with Randolph's studies. In an office practice, use of spring water in glass bottles can be a practical necessity in working out patients' problems. Care must be taken that they are not contaminated by forced chlorination induced by local authorities due to fear of bacterial contamination.
It is important that the clinician perceive these facts and concepts in order to advance our knowledge in inflammatory vascular disease, to help patients who were formerly unsalvageable, and to prevent devastating effects of advanced disease. This, in the long term, will allow a much longer proportion of the clinician's time to be used for preventive medicine and markedly reduce the costs in medicine.
